i ELECTRIC TIME-STAMP.

To all'whom it may concern:

Be it known that I, CHARLES I' S. ELLIS, -av

citizen of the United States, 'anda resident o''Ghicago, in the county of' Gookiand State of Illinois, have invented certain nevv yand by which it ismanipulatedin the manner f oran ordinary hand vstampand provided With ,movablek 'time 'marking elements arranged fin such relation to amarking or' printing dialas to impress upon a paper'or the like the exact "timeo'f its receiptby a Vpersonor inafdepartment of business and carrying suitable magnetically actuated 'clock mechanism for operatingthe movabley time marking'elementsthat isadaptedto be operated vby a suitable velectric connection vWitlran electric clocklorkk other suitableelec,-` tric device forintermittently'advancing the movable time markingelements.

Among the kobjects ofthe/invention is to provide an exceedingly simple, eicient and vcompact stampr lof. this character which ,may

be made at relatively .small costv a'ndvvhich may bei. used in the manner oan ordinary j'handdd'ating stamp, 'and' also, to provide;y a

Y,The tsaid connected plates are attached to and are carried by the upper frame member through the medium of screws 35, andare spaced from the upper member by spacing sleeves surrounding said screws. rl`hey upper pillar plate 32 carries a dialsupporting plate 36 by which to support the dial 18 before referred to.

40 designates the yminute hand arbor which is arranged centrally of theY clock movement frame. At its upper end said arbor 40 carries a minute hand 41r which traverses the dial 18, said hand being ixed y on the arbor. Loosely mounted on the arbor between the upper frameV plate 32 and the dial plate is a gear wheel 42 which is provided with an elongated hub 43 that eX- tends through the dial plate and dial, and to the outer end of which is attached the hour hand 44 which .traverses the dial 1S. The said hour hand gear wheel 42 is driven fromthe arbor 40 through the medium Aof a pinion 45 fixed thereon, the gear wheel 46 meshing with said'pinion` and a pinion 47 carried by the latter gear wheel and meshing with said minute gear wheel. The said minute hand arbor carries at its lower end a time marking element or die 50, made of rubber or like yielding material, ar-

ranged with its free end in the plane of f the lower face of the dial stamp die 26, and by which to mark the minutes. The said minute marking element consists of an elongated fnger having a base portion 51that is clamped in any suitable manner, as by prongs, to a disk 52 that is fixed to the lower end of the minute hand arbor.

designates a gear wheel havingahub 54 which is loosely mountedon the minute hand arbor above the hub of the disk 52. Said gear wheel 53 is driven from the minute hand arbor by means of a pinion 55 iixed to the arbor, .a gear wheel 56V meshing therewith and a pinion 57 fixed centrally to the latter gear wheel and meshing with the gear wheel 53. .The hub 54 of the gear wheel 53 carries a disk 59, which is provided withV holding spurs, or other suitable holding means 60 by which to Vhold in place a second time marking element or die 63 to indicate the hours; said latter time marking element revolving about the central time marking element 50. The said disk 59 may be supported, when stamping pressure is brought on the device, by an `annular flange or ring-like `member V64 atl tached thereto Vand bearing 4against the frame member 33 .and cut away at one side kto receive the gear'wheel 56 and'pinion 57.

.The minute hand arbor is arranged to be given an intermittentmovement through the action of a magnet withinthe casing' that is controlled rom ,an electric clock. or other make and break electric device. As herein shown the means for transmitting a step by step movement to the minute hand arbor is made as follows :-66 designates a ratchet disk whichis loosely mounted on the minute hand arbor 40. Y

67 designates a collary fixed to the arbor, and between said collar and a washer 67 frictionally engaged with said ratchet disk 66 is interposed a spiral compression spring 68,

whereby said ratchet disk is frictionally connected to the'arbor in aV mannerto transmit rotary movement to the arbor, but to permit .to rotate one twelfth the distance of the arbor in Veach intermittent rotative movement ofr the latter.V V The said ratchet diskf is thus intermittently turned orV rotated .through the action ofa pawl 70 that is pivoted atl one end to one end vof a swinging lever 71, pivoted at. 72, to the top pillar plate 32 and arranged beneath said plate 32.V

Said lever 71 is provided near its pawl carrying end with a downturned flange 78, to which is attached an iron plate 74 that constitutes the armature for an electromagf net 75 arranged within the casing adjacentV thereto. A spring 76 which is attached to a lug 77 of the pawlcarrying arm 71 bears at one end against `one of the pillar lposts 84, as shown in Figs. 2 and 4, and normally holds the pawl Vcarrying lever in its forwardmost position. The free end, of the pawl 70` is held engaged with the teeth of the disk 66 by means of a spring 79, engaging at one end the outer side of said pawl between its-pivot and its free end and attached at itsV otheryend to a stud 80 on the pawl carrying lever.

When the magnet'7 5 is energized the arm,`

71. is `drawn toward the magnet, or .away

from the axis of the ratchet disk 66, thereby i carryingthe pawl 70 out of engagement with one of the teeth of said ratchet disk and into engagement with the next rear tooth. When the magnet is denergized the spring 76 acts on the lever 71 to swing it toward the axis othezratchet disk and the spring 79 of the pawl acts .during this. Y time to holdthe pawl engaged with a tooth F of the .ratchet disk so as to advance the said n disk one step in its rotation and to thereby act through the minute arbor 40 to advance the hour and minute hands andV marking elements.

As before stated when the disk is provided with sixty teeth, said diskis adapted to be stepped forward in the manperiphery of thev ratchet disk 66 isa lugy tric clock (not shown).

circuit closing devices located, as for instance, 1n or constitutlng The movement yof the VpawlY carrying i arm .71 under the yiniluence of. thespring 76 is arrested by means of a stop lug'82, whichk is shown as struck downwardly from the pillar plate r32. Located adjacent tothe 83 which isy shown as being struck kdown from the plate 32, and between which and' Y the toothed periphery of the ratchet disk turned in either direction. The disk isheld from backward rotation at a time when the pawl 70A is ridingvbackwardly over the teeth f thereof by means of a holding dog 84 pivoted to the plate 32 and pressed against the .toothedvr disk by means of a spring 85.

The circuit wires 86 of the magnet circuit are led into the casing through a nipple-88 yiixed in. any suitable manner to a yflange 89 struck down from fthe margin of' thev upper pillar plate 32, as shown in Fig. 2, ysaid wires being connected to the coil in any suitable or preferred .mannen v The wires pass through a flexible tube 90 just outside of the nipple `88v to give propery flexible' connection yof Vthe wires with the casing, without permitting said wires to bend too sharply so asto break them.

At one or both sides kof the marking dial is arranged channels to receive aline or lines of type. For instance, at one side of saidfdial maybe arranged a permanent line 92 of type, such, for instance as the word Received, while'at the other side of the 4part of an elec-y base may bearranged a groove 93 to receivey a composed ,line of type, such asa date,
